I know this guy will be unknown largely to the USA audience, but the BBC have recently made a new series of this popular 70's title, and you can see it on the website here.
So what type would you say he was? Cos whilst he's quite a believable character, I imagine an awful lot of people would relate to him.
Seems to me an introvert at least. But yet he craves social interaction. That's about as far as I can get!
(don't worry, I'm not expecting any replies, so I won't be offended)
